To allwlwm it may concern:

Be it known that we, FRED E. Knnre and LUTHER B. WEIDLEIN, citizens ofthe United States, and residents of Youngstown, in the county ofMahoning and State of Ohio, and Cleve and, in the county of Cuyahoga andState of Ohio, respectiveliv, have invented certain new and useful Invements in Dry Gas Cleaners, of which following is a specification.

This invention relates to gas cleaners, and more particularly to dry gascleaners for use in removing particles of coke, o and lime dust, etc.,from the gas coming om blast furnaces, and has for one of its objectsthe provision of such a device that will have a higher efiiciency thanthe cleaners heretofore constructed.

Another object is to provide a cleaner that will not lower thetemperaturfi of the gases any appreciable amount.

Another object is the provision of a cleaner that will have lessresistance than those known in the art, and one thst will re uire verylittle power to operate 1 further and important, object is the provisionof a cleaner having an entirely automatic operation, thereby reducingthe cost of operation to a minimum.

Other objects and advantages of the invention will be readily apparentto those skilled in the art, and will be disclosed in the followingspecification and claims. a

F cleaner shown in Figures 1 to 7 of a series or battery of units Y, allof like construction and operation, so !it will suflice to describe oneunit in detai The numeral 2 designateii the side walls of each of theunits which have a flat top wall 3, and convergin bottom walls 4 and 5which sustain closing bells 6, 7, and 8, thereby forming a closed mainchamber A.

The main hamber or interior of each unit is divided into two sections Band O by transverse walls 9, 9, 10 and 10. The walls 9 and 10 terminatean a preciable wall 3 an converge toward the top, and t e walls 9 and 10converge toward the bottom, forming a sub stantially diamond-shapedsub-chamber 11. Thechamber 11' has an opening in its bottom closed bybell 7 for the discharge of forei meitter which is collected in the chemr, nd gas'exit openings 24 and 25 in its side we ls.

A filter that member 12 is arranged within the chamber 11 and supportedon a flange 15 below the openings 24 and 25. A shaft or rod 13 passesthrough cross supports 01' girders 14, and has its u r end mounted in orconnected with she. mg or vibrating mechanism D, and its-lower endmounted for movement through an aperture in shock receiving member 13'on the mzi't l2, and thereon. The rod 13 is adapted to move freely downthrough the shock receiving member 13 and its head 13" is adapted todeliver an upward vibrating stroke or shock to said member on the upwardstroke or movement of the rod.

Other filter mat members 16 and 17 are supported on flanges 18 and 19secured on the side walls 2, and on the top of the Walls 9 and 10,thereby closing the to of the sections B and C of the main cham r A.

The filter mats 16 and 17 have operatin shafts or rods 20 and 21,respectively, whic have their u per ends mounted in or connected withsliaking or vibrating mechanism Dd, and their lower ends mounted formovement through apertures in shock receiving members 16 and 17 on therespective mats. lhe rods 20 and 21 have heads 20 and 21 respectively ontheir lower ends to deliver an upward vibrating stroke or shock tomembers 16 and 17 on the upward stroke or movement of the rod.

The filter mat members may be of any desired construction, but arepreferably formed of metal w0ol held between two sheets of wire mesh orfabric with suitable support ing or stiffening members.

An inlet main 22 extends along the bat tery of units and has a branchpipe 23 extending into the sub-chamber 11 of each unit below the filtermat 12, through the pipe 23 passes through the filter mat 12 and outthrough the outlet openings or exits 24 and 25, respectively, intosections B and C of the main chamber, then through the mats 16 and 17arranged above the outlets 24 and 25, and into the upper portion of themain chamber A.

The main chamber A has an outlet pipe 26 extending from its upperportion abovethe mats 16 and 17. Pipe 26 has a valve casing 28 mountedintermediate its ends, and a gate or butterfly valve 28 is operativelymounted within the casing so as to be nor- .mally closed by acounterweighted lever 28". The pipe 26 enters or communicates with a gasmain 27 which carries the clean gas to suitable points of distribution.

The vibrators and Dd may be of any preferred construction, and areadapted to e automatically set in motion by, and to receive their powerthrough clutches 35 on the power driven shaft 36 which extendslongitudinally above the battery of units and receives its power fromeither the direct current motor X and its connecting aring 36", or thealternating current motor sll, and its connecting gearing 36".

Clutches 35 are automatically thrown into and withdrawn from operativeengagement at predetermined intervals by'clutch levers 39 which areactuated by c'am melnbers 37 on a shaft 38 which extends parallel toshaft 36, and is constantly driven through gear 38 which is in mesh withgear 38 on the drive shaft 36.

The valve 28 is adapted to-be operated synchronously with the shakingmechanisms D and Dd by means of lever mechanism 29 which is operated bya cam 30 on the shaft 38, which is so positioned and shaped that itholds the lever mechanism and valve in open position for the majorportion of each revolution. but will release the lever mechanism andvalve to the action of the counterweighted lever 28 to close or seat thevalve for a minor portion of each revolution. The

and gas entering' 'or vibrated by means of the rods 13, 21, andvibrating action of the cam 30 is so timed that the valve 28 will bereleased to the action of the counterweighted lever 28' and consequentlyseated at and durin the time the shaking mechanisms D and motion by theengagement of clutches 35, so as to prevent gas passing out of the unitswhile the mats are being cleaned.

The shaking or vibrating mechanisms D and Dd are the same for each ofthe several units.

The 0 aeration of the device as described is as follows- Gas enters theinlet or main 22 from a blast furnace or other source and flows throughthe branch 23 into the sub-chamber 11 and passes upward through thefilter mat 12, thence through the opening or exit 24 and 25 into thechambers B and C, respectively, and thenupward through the filter matmembers 16 and 17 into the upper portion of the main chamber 'A, thenexits through the clean gas or outlet pipe 26, then into the main 27 foruse.

At predetermined intervals the filter mats 12, 16 and 17 will beautomaticallysgaken and mechanism D and Dd to remove the trapped dustand particles of to ,eign matter.

As has been stated, the entire operation of the device is automatic.nism 29 is operated by a cam 30 and butterfly valve 28 closed, andsimultaneously with the closing of the valve 28" the shaking orvibrating mechanism D is automatically set in motionand the dust andother foreign particles are released from the filter mats and falls tothe bottom of the chambers. The dust is removed from the chambers B, C,and 11 by removing the bells or traps 6, 7 and 8, while the gate valve28 is closed.

In Figures 8 and 9 I have shown a modia tied construction of gas cleanerembod ing the general features of my invention. cleaner consists of aplurality of units Yy, 6f, duplicate construction, each of whichconsists of side walls 50, curved top wall 51, and a tapering bottomportion divided by a sharp downwardly sloping wall 52 to form hoppers 53and 54, closed by bells or traps 53 and 54. y

The units are supported in superstructure, composed of suitable uprightsupports 55 set on bases 55 and having a suitable housing 56 arrangedover the tops of the units to house theo ating mechanism.

A single lter mat 57 composed of a plu rality of layers, andconsequently ofiering substantially as much cleaning surface to thegases as the plurality of mats in the ferred form, 18 mounted within theunits d are set in his The lever mecha- 3/ and normally rests betweenthe flanges 58 (it a suitable channel mounted around the in terior ofthe units. The mat is connected to a shaker or vibrating mechanism D bymeans of a rod 59 which has its lower end mounted for movement throughapertures in shock receiving member 6%) on the mat, and is provided wltha head 61, to deliver an upward vibrating stroke or shock to members 60on the upward stroke or movement of the'rod.

The vibrators or shakers D are adapted to be operated at predeterminedintervals by suitable mechanism (not shown) to reclprocatethe rods 59and thereby shake or vibrate the mats to clean them.

A. feed or supply main 62 extends along the battery on one side of theunits, and has a branch 63 entering each unit below the mat 57, and anoutlet main 64 extends along the other side of the battery and is connected to each unit by a branch 65 which enters or. communicates withthe unit above the mat 57.

A gate or butterfly valve 66 is mounted within each branch 65, and isprovided with lever operating mechanism 67 and a counterweighted lever68. The lever 68 is adapted to normally hold the valve 66 closed whilethe lever mechanism 67 is adapted to be operated by a cam 69 on driveshaft of the vibrating mechanism D to open the valve against the actionof the counter- Weighted lever 68 for a predetermined time, and torelease the valve to the action of the counterweighted lever 68simultaneously with the starting of the vibrating mechanism, therebystopping the flow of gas through the unit while the mats are beingcleaned.

The operation of this modified battery of units is automatic, and ingeneral the same as that of the preferred form, with the exception thatgas will only pass through the one filter mat, while in the preferredform it passes through several.
